5 Questions
Why does radiographic film fail to adequately demonstrate slight differences in subject contrast?
Because typical film-screen combinations can only discriminate x-ray intensity differences of 5% to 10%.
How does CT imaging differ from radiography in terms of imaging capabilities?
CT imaging can generate cross-sectional images without superimposition of structures.
What is a key advantage of CT scans over traditional radiography for imaging purposes?
CT scans provide the ability to reformulate images in multiple planes.
How does the sensitivity of CT imaging compare to screen-film recording systems in terms of x-ray attenuation differences?
CT imaging has 10 times higher sensitivity than screen-film recording systems.
Why is it mentioned that CT scans can be used for nondestructive materials testing and studying biological specimens?
To showcase the versatility and applications of CT scans beyond medical imaging.
Learn about the major limitations of radiography, including superimposition of structures on film and the qualitative nature of the process. Discover why distinguishing specific details, especially in cases of similar density structures like tumors, can be challenging.
